A rotaxane‐based Au catalyst was developed and the effect of the mechanical bond on its behavior was studied. Unlike the non‐interlocked thread, the rotaxane requires a catalytically innocent cofactor, the identity of which significantly influences both the yield and diastereoselectivity of the reaction. Under optimized conditions, Au I (the catalyst), Ag I (to abstract the Cl − ligand), and Cu I (the cofactor) combine to produce a catalyst with excellent activity and selectivity.
